Grateful thanks to the people who have replied. I was doing some research for a colleague in South Wales and the Ellen Trigg in question is the one whose parents were Jesse and Ann (nee Hart). Confirmed via baptism record in Glos RO (bap 28/2/1858, Westbury-on-Severn). Details I have also match siblings quoted, viz. Sarah Elizabeth; Thomas; Mary; Jesse; Alice; David and Annie. Again, many thanks. Mark H.
